Product Description

TPRD-1584 - Pass-Reject Base Station Duplexer - 148-174 MHz

The Telewave TPRD-1584 allows the simultaneous operation of a transmitter and receiver into a common antenna. This Pass-Reject duplexer is an ideal choice for systems requiring maximum isolation, with close frequency spacing down to 300KHz. The TPRD-1584 has two Pass-Reject cavities each in the transmitter and receiver sections.

Selectivity and insertion loss may be adjusted by rotating the calibrated connector loops. Telewave duplexers have ¼-inch aluminum top plates which are fully welded to the aluminum outer conductor. As a result of their superior construction, Telewave 8” cavity duplexers achieve greater rejection of transmitter noise and spurious radiation, providing excellent receiver protection. Silver-plated tuners, beryllium copper finger stock contactors, and threaded Invar rods assure maximum temperature stability, higher “Q”, and many years of trouble-free operation.
